What is the purpose of a Slug valve?
It’s quite interesting. I didn’t even know about it… By the way, could you tell me more about the electro-hydraulic actuator? How does it work because I know it tends to have a high initial price? I’ve read information about this on the Internet, but to be honest, I did not really understand all the details, so I would be grateful for your explanations in simple words. In general, any information about the electro hydraulic actuator for valves will be extremely interesting to me for my practical work. I hope for your help. Thank you in advance!
The slug valve stops the flow of product when excessive water is collected in the filter/separator sump. It works in conjunction with the float control valve. The slug valve can also be furnished with “rate of flow ” control which is used to control flow through the filter/separator and with a check valve feature to prevent back-flow.
A slug valve has a cylindrical or conical disc with one or more horizontal hollow passages that can be rotated to open, close, or control the flow of fluid through the valve. The most commonly used type is the two-port open and closed lubricated type. The plug valve is used as a two-position shut-off valve and can provide a tight shutoff. It can be used in various types of liquids and gases, such as air, gas, steam, hydrocarbon, slurries, mud and sewage. The valve plug can be used in vacuum conditions for high pressures and temperatures. A plug valve is used in place of a gate valve where fast response is required. Can be used in high temperature environments. It is sometimes used in conjunction with a globe valve.
